Introduction

The Hybrid Tray Dryer is a batch drying system built for products that need gentle handling, uniform moisture removal and batch-wise traceability. Material is spread on perforated or solid trays, loaded onto trolleys or fixed racks, and exposed to a controlled stream of heated air that sweeps across every tray. What makes the dryer “hybrid” is its energy design. Instead of depending on a single heat source, the unit combines two or more, such as steam or thermic fluid coils working alongside electric heaters, or a heat pump stage running together with conventional heating. This allows plant teams to choose the most economical energy on any given day, hold precise temperature profiles, and keep production going even when one utility is unavailable. For pharmaceutical intermediates, food ingredients, herbal materials, specialty chemicals and many powders and granules, the tray format remains one of the most trusted routes to consistent drying, and the hybrid configuration makes it faster and more economical to operate.

Why Choose Kerone Hybrid Tray Dryer

Kerone has designed and manufactured industrial drying and heating equipment in India since 1976, and that experience shows in how our tray dryers are engineered. Every Hybrid Tray Dryer is sized around your product’s bulk density, initial moisture, target moisture and batch size, not picked from a fixed catalogue. Airflow is balanced through CFD-informed duct and baffle design so that top and bottom trays dry at the same rate, which reduces rejected batches and re-drying. Insulated, leak-tight chambers cut heat loss, while contact parts can be built in SS 304 or SS 316 with smooth, easy-to-clean finishes for hygiene-sensitive industries. Our engineers also advise on the best energy pairing for your site, whether that is steam plus electric, thermic fluid plus electric, or heat pump plus electric, and commission the dryer with documented temperature uniformity checks. Backed by dependable after-sales support and spare parts availability, a Kerone tray dryer is a long-term process asset rather than just a machine.

Types and Features of Hybrid Tray Dryer

Kerone offers the Hybrid Tray Dryer in several configurations to match batch size and process sensitivity. Trolley-type models allow trays to be loaded outside the chamber and rolled in, which shortens turnaround between batches. Static rack models suit smaller laboratory, pilot and R&D requirements. Cross-flow and through-flow airflow patterns are available, and vacuum-assisted or heat pump-assisted versions can be supplied for heat-sensitive materials that must dry at lower temperatures. Heating can be steaming plus electric, thermic fluid plus electric, gas plus electric, or heat pump plus electric. Common features include reversible airflow for uniform drying, PID-based temperature control, HEPA or fine air filtration at the inlet, programmable drying cycles, and optional cGMP-style documentation and data logging. Chambers are fully insulated with a polished or matte stainless steel interior, and capacities range from a few trays for pilot work to large multi-trolley systems for commercial production.

Key Features

  • Dual or multi-source heating (steam, thermic fluid, gas or heat pump with electric) for lower running cost and utility flexibility
  • Uniform temperature distribution across all trays through balanced air circulation and optional reversible airflow
  • Gentle, static drying that protects fragile, crystalline or granular products from breakage and dusting
  • Contact parts in SS 304 or SS 316 with smooth welds for easy cleaning and low contamination risk
  • Programmable PID controller with recipe storage, timers and over-temperature protection
  • Efficient exhaust and fresh-air dampers that control humidity and shorten drying time
  • Thick insulation and sealed doors that minimise heat loss and keep outer surfaces safe to touch
  • Trolley and tray designs customised to batch size, product depth and plant layout

Applications of Hybrid Tray Dryer

Kerone’s Hybrid Tray Dryers are extensively used in industries where batch control, product integrity and consistent final moisture are critical. Typical applications include:
    • Drying of active pharmaceutical ingredients, wet granules and herbal extracts
    • Dehydration of spices, fruits, vegetables, herbs and other food ingredients
    • Drying of dyes, pigments and specialty chemical intermediates
    • Processing of nutraceutical powders, tablets and capsule granules
    • Drying of ceramics, catalysts and small-batch industrial powders
    • Moisture removal from laboratory, pilot-scale and trial-batch materials
For manufacturers who value control, hygiene and repeatability, the Kerone Hybrid Tray Dryer offers a proven batch drying solution with the added advantage of flexible, lower-cost energy use. By blending two heat sources in one well-insulated, evenly ventilated chamber, it reduces drying time, protects product quality and keeps operating costs predictable. With custom engineering, quality construction and long-standing application knowledge from Kerone, it fits easily into pharmaceutical, food, chemical and specialty processing lines.
